I thought I would try to learn GIMP a bit better so I started doodling with the various settings and layer effects to produce this picture:
It is a bit frustrating because a lot of things I know how to do in other software are difficult to figure out in GIMP. For now this is the type of results I can do without doing a lot more learning on the program.
This originally started out as a picture I took with my smartphone and some pencil doodling.
The story that goes with it:
Space aliens get confused trying to find their way around the universe. They try to ask for directions by writing in the pond scum but the locals don't understand them. :D LOL.
